How to disable/hide the navigation buttons after selecting SHOW ALL in RadGrid Paging

[Noel]

I've added the "ALL" option to the PageSizeComboBox in RadGrid.
Very similar to this option: http://www.telerik.com/community/forums/aspnet/grid/how-to-add-show-all-option-in-radgrid-paging.aspx#1697877 

Everything works fine, but when I select 'ALL', the navigation buttons are there. 
Unfortunately, when I click on them, they crash my website.

Is it possible to disable or hide the navigation button in RADGrid Paging when the 'ALL' option is selected?
How can I access the navigation buttons in the server side code. 
I tried using this as somebody in some other thread had mentioned in Item_Created Event:
if (e.Item is GridPagerItem) Button prev = ((Button)e.Item.FindControl("Button1")) 
But it doesnt work. Please help.

Hi Noel,

You could use the following approach to hide the paging buttons:
  mark-up:

<ClientEvents OnGridCreated="gridCreated" />

  JavaScript:

function gridCreated(sender, args) {
    if (sender.get_masterTableView().get_pageCount() <= 1) {
        var gridElement = sender.get_element();
        gridElement.getElementsByClassName("rgPageFirst")[0].style.display = "none";
        gridElement.getElementsByClassName("rgPagePrev")[0].style.display = "none";
        gridElement.getElementsByClassName("rgPageNext")[0].style.display = "none";
        gridElement.getElementsByClassName("rgPageLast")[0].style.display = "none";
    }
}

I hope this will prove helpful.

All the best,
